SPRAYING DEVICE FOR RIMS AND OTHER ARTICLES.

Application filed December 24, 1921. Serial No. 524,624.

I cleaning or treatment agent. The invention comprises a support for bringing said articles into and out of the field of-action of nozzles which project the agent against such articles, and also includes means located partly on said support and partl on a stationary structure, for moving ,t e articles relatively to the said support while exposed to the agent sprayed or projected toward said articles, so that different portions of said articles will be exposed successively to the action of such agent. The invention also consists of other novel features which will be explained in the description following hereinafter, the scope of the invention being 20 indicated in the appended claims.

Reference is to be had to the accompanying drawings illustrating two satisfactory examples of my invention. Fig. 1 is a plan view of one form of my invention, with parts 25 in section; Fig. 2 is an elevation with parts in section substantially on line 2-2 of Fig. 1; Fig. 3 is a vertica section substantially on line 33 of Fig. 1; Figs. 4 and 5 are partial views similarto Figs. 2 and 1 re- 30 spectively, illustrating another embodiment of my invention.

In both forms illustrated, indicates the side walls and 11 an end wall of a building in which the sand-blasting or other opera- 35 tion is to be performed. In said end wall is provided an opening 12, generally of rectangular shape (see Fig. 3) adapted to be substantially closed at times by a vertical wall or partition 13 extending upward along .a diameter of a turntable'14 the center of which is in line with said end wall, at the center of the openin forms a support for t e articles to be treated, and it will be understood that one-half 45 of the turntable projects exteriorly of the building, so that this half may be readily loaded with the articles, when the partition 13- is in line with the end wall 11 as illustrated in the drawings. By giving the turn- -and on said track is 12. This turntable table a half revolution, the articles previously placed thereon are carried into the building, and into co-operative relation to the nozzles and other devices, as will be explained below, the partition 13 again swinging to a position to fit the opening 12 and to reduce the escape of dust, sand, etc, from the building during the operation. The turntable 14 may be supported and rotated in any suitable manner, for instance by making it run on rollers 15 journaled in stationary bearings 16, and by placing on the shaft 17 of the turntable, a spur gear 18 in mesh with a spur pinion 19 on a shaft 20 driven by bevel gearing 21 The turntable 14 preferably has openings so that the sand or other.

agent may fall into a hopper or trough 22 at the bottom of which I have indicated a rotary screw conveyor 23 for carrying the sand away to a place where it will be picked up by elevators or disposed of in any other wellknown or approved manner.

Above the level of the opening 12 and of the partition 13 I have indicated a horizontal overhead track 24, parallel to the end wall 11,

adapted to travel a carone or more nozzles 26, with er connections for supplying (or other agents) to said rlage 25 havin pipes 27 or otfi air and sand nozzles.

At one side of the building I have indicated at 28 an electric motor or other suitable device for driving a shaft 29 which within a box or casing 30 carries a worm 31. So far as described, both forms tion are substantially alike;

In the form illustrated by Figs. 1, 2 and 3. the worm 31 is in mesh with a worm-wheel 32 on a transverse shaft 33 extending into the building, close to the path of the turntable 14. The latter is provided with two pairs of horizontal rollers 34, the axes of which are parallel to the diameter along which the partition 13 is arranged, and the pairs of rollers are arranged on opposite sides of said partition, at equal distances therefrom. At 0 posite ends of the two pairs, the ends of t e rollers 34 car sprocket wheels 35, the two wheels 35'of t e same pair being connected of my inven-.

by a chain 36 which also engages a sprocket wheel 37 on a short shaft 38 carried by the turntable between the roller axes and preferably at a higher level. These short shafts .extend outwardly, toward the edge of the turntable 14, and are provided at their outer ends with clutch members 39 adapted to be engaged with a mating clutch member 40 at the inner end of theshaft 33, it being understood that the shafts 33 and 38 are located at the same level and that the shaft 33 is arranged to align with one or the other of the shafts 38 whenever the turntable 14 has its partition 13 in line with the opening 12 of the end wall 11, see Fig. 1. ,WVhile the shaft 33 is coupled to one of the shafts 38 and rotates this shaft 38 together with tne correspondingrollers 34 and articles, such as rims41, resting on said rollers, the carriage is made to travel along the track 24, ina direction parallel to the said rollers 34 and about centrally over the rims 41 or other articles so as to thoroughly sand-blast or otherwise treat the said articles. It will be understood that a large number of such articles may be placed side by side on the rollers 34. While one set of articles is thus being treated on the rollers 34 which at that time are within the building, the other pair of rollers 34 is outside the building and therefore readily accessible for removing the articles previously treated, and for placing a new set of articles on such pair of rollers.

The operation within the building having been completed, the shaft 38 is disconnected from the shaft 33, the turntable is given half a revolution, and the shaft 38 is coupled to the other shaft 33 which has thus been brought into the operative position.

In the construction illustrated by Figs. 4

resting with the lower portion of their outer peripheries onrollers such as 34, have the upper portions of their inner peripheries in contact with rollers 42, of which there is only one on each side of the partition 13, the axes of,these rollers 42 being in the same general relation to the-turntable as the shafts 33, that is to say, each of these rollers is adapted to align, after the turntable has been rotated successively through angles of 180, with the transverse drive shaft 33 carrying a worm wheel 32' in mesh with the worm 31. The shafts 43 of the rollers 42 are provided at opposite ends with clutch members 39' for co-operation with the clutch than the first, but generally requires .the

member 40 on the shaft 33. In both forms of my invention, the clutch connections 39,

40 and 39', 40 have been indicated only dia-' grammatically, since clutch devices for cou-- pling and uncoupling aligning shafts arewell-known. The second form of my invention is somewhat simpler in construction from, a drive shaft journaled in stationary bearings and into operative relation to which one or the other of said article-revolving means on the turntable is adapted to be brought by the rotation of the turntable, and means for. coupling and uncoupling said shaft to and from said article-revolving means.

2. An apparatus of the character described, comprising a building with an opening in one of its walls, a turntable having a diametral partition to fit said opening, means carried by said turntable and rotatable relatively thereto, to support and revolve articles to be treated, such means being provided in' duplicate, on opposite sides of said partition and at equal distances therefrom, and poweroperated means located within said building with which one or the other of said article revolving means is brought into operative alignment by the rotation of the turntable only when said partition is located within and completely closes said opening.

3. An apparatus of the character described, comprising a movable support, means carried b said su ort and rotatable relaand 5, the rims or like articles 41, instead of y pp tively thereto, to support and revolve articles to be treated, a nozzle-carriage for co-operation with said articles, a rectilinear track for said carriage, and stationary power-controlling means adapted to be brought into operative relation to said article-revolving means by the movement of the support to a position in which said article-revolving means is in operative relation to the nozzle-carria e.

4. An apparatus of the character described, comprising a turntable, means carried by said turntable and rotatable relatively thereto, to support and revolve articles to be treated, stationary power-controlling means, adapted to be brought into and out of operative relation to said article-revolving means by the rotation of the turntable, a stationary track which is parallel to the axis of rotation of said articles at the time said power-controlling means is in operative relation to said article-revolving means, and a nozzle-carriage arranged to travel on said track.

5. An apparatus of the character described, comprising a turntable rotatable about a Vertical axis, article rotating means mounted on said turntable, comprising rollers rotatable upon a horizontal axis means for projectin a spray of. material on said articles, said spray projectin means being movable along a horizontal ine above said turntable, means for rotating said turntable to bring the articles to be treated into alignment-with the spray projecting means and stationary power-controlling means including a clutch, into alignment with which said article rotating means is adapted to be brought only when the articles to be treated are located in alignment with the line along which said spray projecting means is operative. i

In testimony whereof I have signed this specification.
